MACHINE FOR REELING, MEASURING, AND SEVERING TYPE-WRITER OR OTHER RIBBONS.

SPECIFICATION forming part of Letters Patent No. 524,088, dated August 7, 1894;.

Application filed September 23, 1893- Serial No. 486,678. (No model.)

. To all whom it may concern.-

The invention relates to a machine adapted to automatically wind upon one or more drums or barrels, preferably with which the ribbons are marketed, the ribbon of a marketable length from large ribbon holding drums or reels or other sources of supply; and to automatically stop the operationof the machine after a given quantity has been rolled upon the drums or barrels, and, if desired, to at the,

same time automatically sever the ribbon or ribbons thus wound; and the invention relates to various features of construction and organization whereby the ribbons are wound and the mechanism automatically stopped and the cutter, if one be used, automatically operated.

- inafter be made.

While I shall herein describe the invention as applicable to the reeling and measuring of inked ribbons for type-writing machines, I do not limit the invention to such use, as it is applicable to the winding and measuring of ribbons, strips, sheets, or webs of any flexible fabric or material.

In the drawings,-Figure1 is aviewin plan of the machine. Fig. 2is a view in side elevation thereof. Fig. 3 is a view also in side elevation of the side opposite that represented in Fig. 2. Fig. 4 is a view of the machine in vertical central section. Figs. 5, 6, 7, and 8 are detail views to which reference will herecross wise the machine on the dotted line of the disk away from the drum. 7

The machine is organized to reel, measure and sever one or more ribbons, and while in the drawings I have shown it as operating upon six ribbons, I will describe it as though operating upon one only.

Fig. 9 is a vertical section.

The inked ribbon from the ribbon inking apparatus is received from such apparatus upon a drum or barrel A, which is mounted 'upon the stud or shaft (1, upon which it is turned; the said shaft being supported at g each end in bearings having removable hinged caps a, which are adapted to be easily unfastened and to be thrown back upon their hinges to permit the shaft to be removed from the bearing for the'placing of a filleddrurn or barrel and the removal of an empty one. This shaft has at one end a brake drum A, to which attention will be hereinafter directed; the object of the brake drum and its brake being to automatically stop the rota- .tion of the shaft and the drum and ribbon thereon when a receiving reel or drum has been fully wound and the machine automatically stopped.

The inked ribbon B takes the following course through the machine: Unwinding preferably from thelower edge of the roll, it passes under the tension-roll c, thence upward and over the measuring roll 0 between it and the tension roll 0', thence between the knives E E, (see Fig. 4) to the receiving drum or barrel F on the short stud or shaft f (see Fig.

5) extending from one end of a diskf' supported by the arm f extending from the crossrocker-shaft f This drum or barrel is rotated by contact of the positively driven drum G with the edge of the disk f (see Figs. 2 and 3).

The drumG has a drum shaft g which is suitably supported in boxes upon posts or brackets, and has at one end the pulley g over which a driving belt runs. The rocker-shaft f is provided at one'end with a sleeve from which extends an arm f which carries a weight F preferably adjustable upon it, said weight F being an over-balancing weight which over-balances the weight of the shaft f,

the drum thereon, the ribbon, and the disk f.

engagement) and hold the disk f in contact with the roll G through the medium of arm f presently described while the'machine is in operation. The weight arm f is free to turn upon the shaft f a limited distance except when connected with the shaft f by the clutch F This clutch comprises two memthe outer end of the sleeve from which the arm f extends. The other member. f is attached to the shaft f by afast feather, but is arranged toslidelongitudinally thereon. The

operation of this part of the device is as follows: When the two members of the clutch are engaged as represented in Fig. 1, the weight F then over-balances the diskf and its parts, and the disk is liftedvagainst the drum Gto the position represented .in Fig. 4.

It will be understood that the arm f is not secured to the shaft f but is free to swing upon it, and that the lifting action is produced by means of another arm f which is fast to the shaft f and is moved by it; this arm preferably having at its outer end alateral extension or nut f and an adjusting screw f which is adapted to be brought-in contact with the under'edge of the armf when the shaftf has been turned by the weight F"; and this movement of the arm f by the weight causes the arm f disk f, &c., to be lifted until the edge of the disk has been brought into contact with the drum G, and it also serves to hold the parts in this position until the weight F has been released by the disengagement of the member f of the clutch from the member 1, and when this takes place, the arm f falls upon its stop or rest f (see Fig. 3) and the weight F no longer exerts an over-balancing effect on the arm f; the disk f and its parts then being the overbalancing parts, fall away from the roll G,or to the position represented in Fig. 10, thereby immediately stopping the further rotation of the disk f and' the winding of the ribbon upon the drum or barrel carried by it. This action of the clutch, weight, and disk takes place automatically and after the winding of the desired length of ribbon upon its barrel or drum, the result being reached, as above indicated, by the automatic disengagement of the member f of the clutch from the member f The lower knife E is stationary, and is held by a suitable cross-support e. The upper knife E is movable, and is secured to a lever c. This lever is preferably quite heavy, and is pivoted at its rearend b to an upright,and its forward end slides in the guide-way a (See Fig. 2). Its forwardend is held in elevated position by the latch e which is represented in the form of ahook pivoted at e and having the end (2 to close under the outer end of the pivoted bar. It is the downward movement of this bar that causes the automatic stopping of the machine and the severing of the measured ribbon. As above intimated, however, the knives may be dispensed with; but this would not interfere with the use of the knife-bar or lever in its capacity as a.'stopping device. The pivoted end of said knife bar or lever is connected with the brake of the drum A and with the clutch of the rocker-shaft f and with the clutch of the winding roll hereinafter referred to, in such manner that upon its release by the latch and fall, it automatically sets the brake upon the drum A, disengages the member f of the clutch from the member f and permits the disk f and the wound reel of ribbon to drop from the drum G and releases or withdraws the clutch from the winding roll to be described. Before specifying these various connecting devices, I will describe the mechanism which controls the operation of the latch e and which includes the winding drum above referred to. The measuring rollC has a shaft 0 supported in suitable bearings, and one end of which carries the bevel pinion c which meshes the bevel pinion c on the drum shaft 0 The drum 0' has a chain cord c attached to it which is wound upon the drum as the shaft 0 is revolved.

The chain or. cord has at its lower end a weight 0 for putting tension upon it and for unwinding it from the drum, as will hereinafter be described, and the cord passes overv a roller 0 which serves to guide or lay it regularly upon the drum as it is wound.

The cord carries an adjustable tappet or finger 0 which as it is wound comes into contact with a lever o pivoted at 0 (see Fig. 2) 9 and connected with the latch e by the long link 0 and lifts it sufficiently to disengage the latch from the knife bar 6' and this releases the knife bar and permits it to drop.

This tappet or finger 0 may consist of aring open at one side and having its ends connected by a bolt or screw 0 (see Figs. 2 and 3) to clamp it in position on the cord.

The passing of the ribbon B over the measuring roll 0 of course causes it to be rotated, and this rotation is communicated to the drum 0, and the winding of the cord 0 by the drum until the adjustable tappet is brought into play causes the lever o to be moved and the bar a to be dropped at any pro-determined interval or when any desired length of ribbon has been rolled upon the barrel or roll F. I To actuate the brake of the drum A by this movement of the lever e, a lever H is pivoted at h and its end h connected with a rock lever h projecting from rock-shaft M. (See Fig. 9.) Its other end 72. (see Fig. 3) bears against the stop or buffer 72. on the end of the brake strap 77. and upon the fall of the lever bar e the end h of the lever (through the parts m and M presently described) is raised, and the end 71. depressed, causing the brake strap 72. to be drawn upon the brake drum A, and exert a braking action upon it. The clutch member-f is disengaged from the clutch member f of the rocker-shaft f 3 upon the fall of the lever bar e, by means of the lever m upon the end of the rock shaft M, this lever extending upward to a position to be moved outward by a projection uponlthe end of the lever bar e (see Fig.

9). This rock shaft Malso carries a clutch lever m (see Fig. 3) the upper end of which is in the form of a yoke and has studs to enter a groove in the section f of the clutch. A spring m serves to move the section f of V the clutch toward the section f and hold the lever m in operative relation with the end of the lever bar e. Upon the downward movement of the lever bar e, the leverm is moved outward, therefore turning the shaft M and causing the clutch lever m to also be moved outward'and to move the member f of the clutch from the member f".

To permit the cord to unwind after the operation of the latch e, as above specified, the drum 0 is fastenedto the shaft 0 by the friction clutch N, the drum being free to turn on the shaft 0 and the clutch N being secured to it by a fast feather and bearing against one end of the drum. It is held in contact therewith by a spring n; it is removed from contact therewith by the lever n which is pivoted at 01 and the end 72. of

which is in operative relation to the cam pro-.

jection n on the pivot end of the lever bar c, so that upon the release of the lever bar e, the projection'n coming in contact with the end n of the lever causes it to remove the clutch M from the barrel 0, and the weight then causes the cord to be unwound.

To restore the clutch N, release the brake from the drum A and permit'the engagement of the members f f of the clutch, the lever bar e, is lifted by hand until it is automatically engaged by the latch e The arm f is then lifted sufficiently to permit the engagement of the sections f f of .the clutch and their releasespermits the weight F to lift the disk f 'and the barrel F, and this of course causes the operation of the machine.

To receive a form of drum or barrel which I prefer in some instances to employ, I have provided the stud f with a surrounding barrel which'is slitted and which is of a size to receive the removable slitted barrel F. The barrel F is placed uponthe permanent barrel with the slits in line and the ribbon having the hooks 0 attached to its end preferably by an uninked section is engaged with the removable.

barrel by entering the hooks in the slit.

In use, a roll of inked ribbon is placed upon the shaft 0. and its end carried about the roll 0 over'the measuring roll 0, beneath the lever c to the drum F, and the machine is then put in operation as above indicated, the ribbon reeled, and measured, and the machine automatically stopped.

The buffer 71.", Fig. 3, preferably is made of rubber, although it may be in the form of a metal spring. There is a washer h between it and the end of the lever H. The office of the bufier is to relieve the lever I-I and the brake strap h from undue strain.
